u IMPROVEMENT IN'DEVJICE FOR,PREVENTING THE UNCOUPLING- VOIE' CLTCHES IN SPINNING-MULES.

,Thevschedule referred to in' these Letters Patent and making part of the same.

We, HEZEKIAH MAooN and JOSHUA HUNT, of Providence, Rhode Island','have invented a Device for Preventing` the Clutches on Mule-.Heads from springing apart, of which the following is a specication.

\ In the accompanying drawing- Figure 1 is aview` ot' the clutches, lever, collar, and spindle in position when the carriage is returning to the mule-head. Figure 2, View of the position of the clutches, le-

'mule-head.

Figure 3, perspectiveview of lever, with the arm M, the fulcrum K, the pin P, the weight H, and 'the movable headG'. Q MAs the clutches B and Uinterlock to change the ver, &c., when the carriage has started away from the direction of Vthe travel of the mule-carriage, it often happens that the force which throwsthem together reacts and throws them apart again, by which great damageV is done by `breaking of yarn. Some device haslong been desired to prevent this happening, and the one herein described `accomplishes thepurposc,

and operates as follows:

We make the lever M of wood, or of iron or other metal, either 'casting or attaching a weight, H, at one end,

and a head, G, just abovethe weight. Between the head and weight we place a spiral spring, or apiece of rubber, of Y sucient power to throw the head up and nearly out of t-he'guides` when relieved of resistance.

We tix a fulcrum-spindle at K, and 'through the spindle we'place a little pin, IP, which works within a groove cnt in the lever, and governs its traverse so that it shall remain in a position to be acted. upon by the carriage.

In iig. 1A the posi tions of theparts are-shown when the `carriage is coming toward the head, -The device is attached to the upright of the frame by the fulcrum-spindle K, and i's held `imposition bythe pin P.

The carriage strikes the arm M and pushes it down, thus raising the other end4 of the lever till the head G strikes the shoulder S of the sliding clutch, and bearing against this shoulder the head is pressed down within the guides, and toward the weight H.

lhe movable clutch G being carried toward, and interlocked with B, removes the shoulder S from the head G, which, by action ot' the spring, is thrown in behind the shoulder S, and against its shaft, thus lling the space and holding the clutch C in position,

as shown in hg?, preventing a possibilityof a spring-v Claim.

What we claim as our invention, and desire to se-.

cure by Letters Patent, is

The combination ofthe head G, the weight H, the piu I, andthe lever M, all applied and operating as descrbed,'for preventing the clutches of mule-heads from springing apart. v
